Description

Method and device for performing interference measurement on interference measurement resources

The present invention relates to Long Term Evolution (LTE) communication technology, and more particularly to a method and apparatus for performing interference measurement on interference measurement resources. Background technique

The Long Term Evolution (LTE) system has been researching R12 technology accurately after several versions of R8/9/10/11. At present, some R8 products are gradually commercialized, and R9 and R10 are subject to further product planning.

After the R8 and R9 phases, R10 adds many new features to the former two, such as: Demodulation Reference Signal (DMRS), Channel State Information Reference Signal (CSI-RS, Channel State) Information Reference Signal) and other pilot characteristics and transmission and feedback characteristics such as 8 antenna support, especially the inter-cell interference cancellation enhancement (elCIC, ehanced Inter-Cell Interference Cancellin) technology is based on the R8/9 ICIC. Further consider the interference avoidance technique between cells. The technology for solving the interference problem between cells mainly considers the cell interference avoidance under the isomorphic network in the initial stage of the R10 phase, and the mainstream considers the eCIC technology and the Coordinated Multi-point (CoMP) technology. CoMP means that multiple nodes cooperate to send data to one or more user equipments (UEs) at the same time-frequency resource or different time-frequency resources. CoMP technology can reduce interference between cells, improve throughput at the cell edge, and expand cell coverage. However, due to the introduction of more scenarios in the heterogeneous network in the later stage of the discussion, the complexity of the CoMP technology and the time limit of the R10 discussion, it was decided not to introduce additional CoMP standardization content in the R10 phase, but the design of the CSI-RS can be considered. The CoMP part was designed to be designed, so CoMP technology did not go deeper after the 60bis meeting. The configuration information of the RIO CSI-RS mainly includes non-zero power CSI-RS configuration signaling and zero-power CSI-RS configuration signaling. The non-zero-power CSI-RS configuration mainly considers the time-frequency resource location of each non-zero-power CSI-RS in one subframe by using a table index, as shown in Table 1 and Table 2, where Table 1 gives The resource mapping of the CSI-RS in the normal cyclic prefix subframe configuration is shown. Table 2 shows the resource mapping of the CSI-RS in the extended cyclic prefix subframe configuration; the terminal side non-zero power CSI-RS is notified by the number of antenna port configurations. The number of occupied time-frequency resources and the corresponding antenna port, and the position of the subframe receiving the CSI-RS by the terminal side using the subframe offset and the periodic index, such as the CSI-RS subframe configuration shown in Table 3.

Table 1

Table 2

table 3

The zero-power CSI-RS uses a 16-bit bitmap sequence to inform the terminal side of the resource elements that need rate matching. As shown in Table 3, the subframe offset and period of the CSI-RS are used to inform the subframe where the terminal side zero-power CSI-RS is located.

The purpose of the non-zero power CSI-RS is mainly to let the terminal side measure the CSI and feed back to the base station side. The main purpose of the zero-power CSI-RS is to reduce the interference of the data service to the CSI-RS and thereby improve the accuracy of measuring the CSI. After the base station side notifies the terminal-side zero-power CSI-RS resource location, The terminal side assumes that the base station side does not place a PDSCH or other reference signal or channel at the resource location of the zero-power CSI-RS.

R11 needs to consider the impact of CoMP technology on the standard, especially the configuration of interference measurement resources and zero-power CSI-RS resource configuration. As discussed at the latest R11 conference, using zero-power CSI-RS resources to measure interference can provide more accurate interference estimation performance, and can also be partially compatible with R10 version terminals. After the zero-power CSI-RS is used to measure the interference in the R11 phase, the rate matching resources that need to be identified on the terminal side need to include the following three types:

1. Non-zero power CSI-RS resources;

The base station side sends non-zero-power CSI-RSs in an 8-port or 4-port manner. The terminal side can only support 4-port or 2-port non-zero-power CSI-RS. In this case, zero power is required at other unrecognized port locations. CSI-RS performs rate matching; or the base station side transmits non-zero-power CSI-RS, and the terminal side uses feedback mode 1-0, or 2-0, or 3-0 to identify non-zero-power CSI-RS. To identify a port with a non-zero power CSI-RS, you only need to configure the port that identifies the zero-power CSI-RS.

2. Zero-power CSI-RS resources that reduce interference of data traffic for CSI-RS measurements;

3. The terminal side measures the interfered zero-power CSI-RS resource at the corresponding resource location.

For the first type and the second type of rate matching resources, the purpose of configuring the zero-power CSI-RS is the same for R11 and R10, and the third type of rate matching resource is newly added by R11, so that a new zero-power CSI needs to be present for R11. The RS configuration mode enables the R11 zero-power CSI-RS to include at least two parts, one for interference measurement and one for rate matching, and the current R11 has no interference measurement scheme for zero-power CSI-RS for interference measurement. In this paper, the zero-power CSI-RS of the interference measurement is called Interference Measurement Resource (IMI), and the zero-power CSI-RS of the rate matching is called Rate Matching Resource (RMR).
